REFBIGERATING- APPARATUS FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Dec. 15,1914.

Application filed (lctober 31, 1910. Serial No. 589,927.

To all whom it may concern Be it known that I, THOMAS HENRY GAR- LAND, aresident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Refrigerating Apparatusfor Railway-Cars, of which the following'is a full, clear, and precisespecification.

My invention relates to cooling or refrigcrating apparatus for railwaycars and may be considered as an improvement over the arrangements shownin my Patent No. 978,284, issued December 13, 1910, and among theimportant objects are to provide improved means for circulating cool airthrough the car and about the contents to be protected, and to provideimproved means for protecting the cold water circulating piping againstentrance of cinders, dirt, and solid particles liberated by the meltingice.

The various features of my invention are fully disclosed in thefollowing specification together with the accompanying; drawings, inwhich drawings Figure 1 is an elevational view in longitudinal verticalsection of a car, traveling toward the left, Fig. 2, is an enlarged viewtaken substantially from plane 2.2, Fig. 1, Fig. 3 is a sectional viewtaken from plane 33, Fig. 2, and Fig. at is. a sectional View taken fromplane il-at, Fig. 2.

The car shown, particularly Fig. 1, has in general the same constructionas in my patent referred to. The car comprises a supporting base orstructure 1 supporting the main floor 2, the side and end walls 3 and 4respectively and the roof 5, the sides, ends and roof walls beingpreferably double, as shown, to afford better heat insulation in thewell known manner. Adjacent each end wall of the car is a bulk head orintermediate wall 6 also preferably of double construction, each bulkhead with the adjacent car end wall forming a compartment 7 forreceiving ice through hatchways 8 in the car roof adapted to be closedby hatch covers 9.

Near the bottom of each ice compartment is a grid frame 10 forsupporting the ice, and below the grid frame is supported a well 11 forreceiving the ice water. Arranged along the'car floor 2 is the piping12, whose ends connect with the wells 11 to receive the ice water, theflow from the wells being con-.

of condensed steam when the piping is connected with steam supply tocause heatingof the car. Above the piping is arranged the lattice orgrille work floor 19. Each end wall a at the upper end of the icecompartment has an opening 20 leading into the entrance end of adownchute 21, which terminates in the compartment between the car floorand the well 11. As shown, each opening 20 is controlled by adoor 22adapted to seat in the outer edge of the opening 20. The outer end ofeach opening 20 is hooded over by an intake chute 23 secured to theexterior of the car end and extendingv vertically upwardly above the carroof, and having mounted at its entrance end a swinging hood 2 f pivotedon a rod 25 supported at the upper end of the chute. \Vhen the car is inmotion the hoods at each end scoop up fresh air and deflect itdownwardly through the intake chutes 23 and thence through openings 20,if the doors 22 are; open, the opening and closing of the door beingcontrolled by levers 26.

The inner wall of each down chute 21 opposite the opening .20 has anopening 38 controlled by a door 39 preferab1y hinged at 2' along itsupper edge and having the hasp 40 at its lower edge for engagement withstaples 11 and 42 secured respectively adjacent the opening 38 and tothe roof of the car, so that the door 39 may be locked in either closedor open position. Each bulk head 6 opposite the opening 38 in theadjacent down chute has an opening 43 connecting the ice compartmentwith the interior of the car near the top thereof, and

each bulk head near its lower end has an opening 44; for connecting thecompartment between the grille floor 10 and wellll with the interior ofthe car near the bottom thereof.

Bananas are usually transported in refrigerator cars without the use ofice,'ample ventilation only being required. In addiice in the bunkers(under refrigeration) it tion to the ventilation obtained through theair chutes 21, it is desirable to obtain a circulation of air throughthe ice hatch openings 9 by leaving the hatch covers open.

in bulk, from blocking up theopening 44 and thus preventing the air fromthe ice compartment from passing down to the.

space under the grille floor 19, an apron 45 is provided, this apronbeing'hinged along the upper edge at y' to the bulk head above theopening 44. When the car is to be used for bananas without ice in thetanks, the apron 45 is dropped down against the grille floor 19. Whenthe car is to be used with ice in the tanks, the apron is raised to heagainst the bulk head.

'When the car is loaded with bananas the outside air enters the forwardend of the car through the hood and ice hatch openings,-

thence down through the chute and ice compartment to the space betweenthe floors 2 and 19 of the car, along between the floors to the rearend, then up through thereai is desirable that the heat and gases givenofi by the fruit be withdrawn from the car until the fruit is cooleddown to the proper temperature. To accomplish this, the exhaustventilators 46 on the roof of the car are opened and'the doors 22 in theair intakes are opened. The hoods 24 at each end are turned to face theforward movement of the car. Air will be deflected by the hoods 24 downand through the open doors 22 into the chute 21, thence to the spacebetween the fioors 2 and 19 of the car. Nearly all kinds of fruit areshipped in crates or boxes and are so loaded into cars that there willbe spaces between the crates or boxes for the circulation of air. Theair, therefore, that is taken in at each end of the car and conducted tothe space between the floors 2 and 19, isforced and drawn by the exhaustventilators upwardly throughthe grille fioor and between the crates orboxes of fruit, and discharged to the exterior through the exhaustventilators on the roof of the car, carrying with it the heat and gasesgiven off by the fruit. The ventilators and air intakes are kept openfor the first 100 or 200 miles,

In order to keep the bananas, which are loaded until the fruit issufficiently cooled, and then closed, the car making the remainder ofthe trip without air circulating through the car, l

A largepercentage of fruit is transported in refrigerator cars withoutusing ice in the bunkers, the preservation of the fruit beingaccomplished by keeping a free circulation of fresh air passing throughthe car. 'When shipments are to'be so transported, the ventilators andair intakes are usually kept open through to destination, except whenthe temperature falls below the freezing point, when the openings areclosed.

There are times when a greater supply of air is required to ass over thefruit through the opening 43 t an is supplied bythe ice hatches. Thedoor 39 can then be opened and the air taken in through the hood, andopening 20 can be passed directly through the ice compartment, andopening 43 over the fruit. This door 39 also gives access to the door 22in case repairs are required' In Figs. 2, 3, and 4, a desiredarrangement is shown for the lower portion of the ice compartments. Ithas been found that some protection must be made against the clogging upof the water pipes by cinders or other foreign'matter entering throughthe hoods. The floor 47 below the ice grid 10'; is constructed to form atrough 48 extend' ing the full length "of the fioor for receiving thecinders and primarily the greater partof the water from the melting ice,the water and cinders being deflected into this trough by aprons 49 and50 hung from the car end between the carsides and the chute21, and theapron 51 receiving from the aprons 49 and 50 and extending between thecar sides 1n front of the chute 21. Below the apron 51 the floor isdepressed to form the well 11,

into which well extends the entrance end 12 of the piping 12. Thecinders and other 7 solld matters will remain in the trough 48 while theover-flow water from this trough Wlll flow over the ridge 52 between thetrough and well and into the well, and when 7 i the water in the wellreaches the properlevel I 1t Wlll flow into the entrance end 12 and intopiping 12. As a further protection the well is covered by a screen 53.

Other changes and modifications areof course possible which would stillcome'with in the scope of my invention, and I do-not therefore desire tobe limited to the precise constructions and arrangements shown, and Itherefore claim the following:

In a railway car, the combination of an ice compartment, a grate 1n sald1ce compartment for supportmg the lee therein, a floor below said grate,a trough in said floor extending full length of the ice compartment,over-lapping aprons below said grate for defleeting the water of themelted ice and cinders and other foreign particles into said my namethis 27th day of October, DL, trough, a well formed in said flooradjacent 1910. said trough and below said aprons for receiving the waterover-flowing from said THOMAS HENRY GARLAND trough, circulating pipinghaving an inlet Witnesses: end in said well, and a screen over saidWell.
